End-to-end OpenShift cluster creation using Red Hat Assisted Installer. Handles Single-Node OpenShift (SNO) and HA multi-node clusters on baremetal, vsphere, oci, nutanix. Use when: - "Create a new OpenShift cluster" - "Install OpenShift on my servers" - "Set up a single-node cluster for edge deployment" - "Deploy a production HA cluster" Complete workflow: cluster definition, ISO generation, host discovery/validation, role assignment, network configuration (VIPs, static networking), installation monitoring, credential retrieval. NOT for: - Listing existing clusters → Use `/cluster-inventory` skill - Modifying running clusters → Out of scope (Day-2 operations require direct cluster access) - Cluster upgrades (not yet supported)
